B REECH-LOADING FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 372,684, dated November 8, 1887.

Application filed June 6, 1887. Serial No. 240,403.

To all whom it 11mg concern:

Be it known that I, DANIEL M. LEFEVER, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Breech-Loading Fire- Arms, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in breech-loading fire-arms of the class termed hammerless, in which a concealed hammer is located within the frame of the breech; and the object is to so construct and arrange the automatic cocking mechanism that the parts are kept in close contact and the wear thereof compensated, so that the hammers may be automatically thrown up or cooked when the arm is broken; and to this end the invention consists in the detail construction and arrangement of the parts, all as hereinafter fully described, and pointed out in the claims.

In specifying my invention reference is had to the accompanying drawings, like letters indicating corresponding parts in all the views, in which- Figure 1 illustrates abreech-loading arm of the above-mentioned class, the said plate being broken away to show the cocking-rod bearing against the hammer, and the metal of the breech-extension being broken away for the purpose of illustrating the compensating devices at the outer end of the cocking-arm, the dotted lines showing the barrels tilted on the hinge-pin and the hammer thrown back. Fig. 2 is a like view,'partiallyin section, illustrating a modified construction and arrangement of the cocking-rod and hammer, the full lines showing the barrelslocked and the dotted lines showing the barrels tilted on the hingepin, as in Fig. 1. Fig. 3'illustrates the construction and arrangement of the cocking'rods in relative position for a double-barreled arm of the above-mentioned class, and Fig. 4i1lustrates an enlarged detached view of the hammer and the cranks constituting the inner and outer ends of the cocking-rod in the construe tion illustrated in Fig. 2.

A represents an armof the socalled hammerless class, and may be constructed in any desirable form so far as relates to the top fastenings and other parts of the arm, with the (No model.)

in the operation of breaking the arm, and S is the stock.

All of these parts may be of any desired construction, since they form no part of my present invention.

a is the so-called concealed hammer located within the breech-frame upon the pivot a. The hammer a is provided with an offset or shoulder, 0, against which the inner end, b, of

the rod 1) bears. The red 1; extends lengthwise through the breech-extension of the arm, as best shown in Figs. 1 and 2 and its outer end, (1, extends in close proximity to the fore-. end strap, and the screw s, passing through a threaded socket in the fore-end strap, bears against theouter end, d, of the said rod b. The rod 12, bearing against the shoulder or offset 0 of the hammer a at one end, and against the screw 8 in the fore-end strap at its other end, serves to throw up or cock the hainmera when the barrel B is tilted on the hinge-pin of the arm, and this result is secured by the impingement of the screw on the end d of the rod 1).

The object of providing the screw 8 to bear on the end 61 of the rod b is to provide an adjustable bearing in'the fore-end strap against the rod 1) to cock the hammers, in order that the opposite extremity of the rod b may be kept in close contact with the shoulder or offset 0 of the hammer and the wear on the cocking-rod compensated, and this construction secures the desired result, and thereby secures a positive and effective means, reliable and very durable, to cook the hammers automatically as the barrels are tilted on the hinge-pin.

It will be observed that the end d of the rod 1) is inclined or wedge-shaped, and that in the construction illustrated in Fig. 1 the rod 1) operates on the hammer a by being pushed as the barrel B is tilted on the hinge-pin; but I do not restrict myself to this arrangement of the parts, since the same result may be secured by the construction illustrated in Fig. 2, in which the rodb turns in its seat in the breechextension D, and the ends I) and d constitute cranks exerting their force on the hammer by the rotation of the rod 1) as the barrels tilt on the hinge-pin, instead of moving rearward, as in the construction illustrated in Fig. 1. The end of the rod 1) bears against the offset or shoulder a of the hammer a, and the screw 8, passing through the fore-end strap F, bears against the outer end, (Z, of the rod b, as best shown in Fig. 4-, where it will be observed that as the barrel B tilts on the hinge-pin the screw 8 bears the end (1 of the rod b downward, causing the rod b to turn in its seat in the breech-extension D and forcing its inner end, I), to bear upward on the hammer a, thus throwing it up or cocking it and securing the desired result; but it will be observed that in both forms of construction the essential feature consists in the rod 1) extended lengthwise through the breeclrextension of the arm, with 7 its inner end bearing against the hammer and All of the foregoing difficulties are overcome by myinvention, and the eocking1nechanism is rendered positive and very durable.

At Fig. 3 of the drawings I have illustrated the mechanism shown in Fig. 2 in relative position for use in a double-barreled arm, and the only difference consists in arranging the bends of the ends I) and d of the rod 1), as shown in said Fig. 3.

Having thus fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. In a breechloading fire-arm, the combination of the hammer with a rod extended lengthwise through the breech-extension ofthe arm, its inner end bearing against the ham-- nier, and a screw in the fore end strap bearing directly on the outer end of the rod, whereby the screw serves to keep the rod in contact with the hammer and compensate the wear, substantially as and for the purpose set forth.

2. The combination of an adjusting-screw in the fore-end strap of the arm, bearing directly against the rod for cocking the hammer, the hammer provided with a projection or offset, 0, against which the rod bears, and the cock ing-rod, substantially as and for the purpose set forth.

In testimony whereofI have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 4th day of June, 1887.
